Juuki Ningen Jumbor

In the year 3002, human civilization had risen and fallen repeatedly over the millennia, enduring relentless destruction and hardship brought by a savage natural world. In this age of constant struggle against nature’s fury, construction teams emerged as the driving force of the economy—both conquerors and weapons in their own right, as heavy robots were employed in construction to maximize efficiency. Jumbor led a renowned construction team serving a small nation ruled by a beloved young princess. One day, as his crew prepared to rebuild a tunnel destroyed by an earthquake, a far more powerful construction team arrived, swiftly seized the territory, and brutally killed Jumbor when he tried to protect his comrades. Jumbor awoke in the year 3007, resurrected in a cloned body of his own design, with transplanted memories and a physical age of just five years old. His new form was partly mechanized, featuring robotic arms linked directly to signals from his brain. He learned that his homeland had fallen, and that the princess and king had vanished. He soon discovered that his mechanized body possessed immense power, and was told that he was the "last of the series."
